2.9.9:

Gtk:
* PrintOperation: get_print_settings(): Ref the return to avoid a crash.
  (Marko Anastasov)
* RecentManager: Change add_fullI to add_item(), overloading according to the 
  parameters. (Jonathon Jongsma)
* SpinButton: Added "wrapped" signal, without a default signal handler, to 
  preserve ABI. (Murray Cumming)
* Widget:
  - Correct the new composited_changed signal to avoid breaking ABI.
  (Murray Cumming)
  Bug #348241 from Daniel Holbach.
  - Fixed a typo so that input_shape_combine_mask() is really wrapped.
  (Marko Anastasov)
* Build: Build with the new glibmm --enable-api-default-signal-handlers=no 
  option for reduced-resources embedded devices. (Murray Cumming)

Documentation:
* Printing examples: Use the new gdkmm cairo methods instead of the 
  C functions. (Marko Anastasov)
